Umbrella_android - Digital And Physical Security Advice App

Umbrella is an Android mobile app developed by Security First that provides human rights defenders with the information on what to do in any given security situation and the tools to do it. It allows the user to choose what they want to do, such as: protect data; securely make a call/email; securely access the internet; plan secure travel; protect their office/home; conduct counter-surveillance; or deal with kidnapping, arrest or evacuation. Once a situation is chosen, the app outlines what to do and what tools to use given your circumstances. This is followed by a simple checklist of recommended actions that can be customised, saved and shared securely. Umbrella’s Feed also provides users with an up-to-the-minute account of potential risks in their chosen location.

Example Usage

Umbrella is designed for everyone (people looking to increase their security, folks living in high-risk areas, regular travellers, business people, techies, journalists, NGO staff, aid workers, human rights defenders, social workers, environmental activists, etc).

However, when we built Umbrella we tried to keep in mind the story of Glen Greenwald and Edward Snowden. Greenwald couldn't communicate with Snowden at the start because he found it cumbersome to set up encryption (he nearly missed one of the biggest stories of the decade because of this!). Also, when he (and Laura Poitras) travelled to Hong Kong - they didn't have much knowledge about how to meet securely with Snowden and detect surveillance. This is a common problem for journalists and activists. Umbrella is designed to solve this problem (and others) by having nearly everything they would have needed to know in one place - in their pocket.

Main Parts of Umbrella

Introduction: This is the part the user sees first. It explains briefly how the app works and the basic terms and conditions.

Menu: The bottom navigation menu is the main way for a user to navigate. It lists the feed, forms, lessons (with tool guides), checklists and account.

Feed: The feed contains security feeds from places like the UN Relief Web and the US Centers for Disease Control. You enter your location (and how often you want to be updated). Every a new update is released (e.g a disease outbreak in your location), the information comes up on the dashboard.

Lessons: Lessons are where users can learn about topics and things that they can do to improve their security. Some of the lessons have different levels (Beginner, Advanced, Expert) depending on your needs, ability, and risk. Each module is broken down into sections. At the end of each module is a list of other resources and further reading.

Tool Guides: These are detailed guides about how to use software and apps mentioned in the lessons.

Checklists: Checklists are quick and easy references to help users implement the advice in the lessons. You can tick them off as you complete each item. Items can be edited. You may also create custom checklists. If you start ticking a checklist, you will then see them on the Checklists page. Checklists can also be shared through other apps such as your email.

Forms: Forms allow a user to quickly fill out and share important information about issues such as their travel plan in a high-risk location or report on a digital/physical security incident.


The general flow of lessons is presented in order to replicate the typical way that a user works. Protecting their information -> Communicating with other people -> Arranging and travelling to a location -> Doing their operations and work -> Dealing with personal issues that may arise-> Seeking support if something goes wrong.

Dashboard Feed Sources

These are the sources that we currently include for real-time updated security Feeds. For privacy reasons, users never connect directly to these services. We are always looking for more useful sources that will help users keep updated on the move.


Navigate to the "Account" from the bottom menu. Here you can:

  • Modify settings (feed interval, feed location, feed sources, notifications, connections, import data, export data)
  • Enable Mask
  • Set a password
  • Log out


You need an Android phone with a minimum version of 4.0.3 (SDK 15 - ICE_CREAM_SANDWICH_MR1)
